More about phratry:
The Greek word for "phratry" means "his brother." Around the second century BC, at the beginning of the human era, there was a divide of Greek tribes known as the Phratry. Their relationship was one of brotherhood and shared kinship. People from the same caste, for instance, could fall into this group under the current circumstances.
Phratry supremacy was observed during the Dark Ages, but it declined in importance during the Classical era. Due to this age, other influential groups, such as political parties and churches, are forming. Political party supremacy is still evident everywhere today.
